Method Details

getBeginCap
boolean getBeginCap()Provide boolean value from initializeOnly SFBool field named beginCap.
Tooltip: Whether beginning cap is drawn (similar to Cylinder top cap). Warning: since this field has accessType initializeOnly, the value cannot be changed after initial creation.
 Returns:
 value of beginCap field

setBeginCap
Accessor method to assign boolean value to initializeOnly SFBool field named beginCap.
Tooltip: Whether beginning cap is drawn (similar to Cylinder top cap). Warning: since this field has accessType initializeOnly, the value cannot be changed after initial creation.
 Parameters:
newValue
 is new value for the beginCap field. Returns:
Extrusion
 namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

getCcw
boolean getCcw()Provide boolean value from initializeOnly SFBool field named ccw.
Tooltip: The ccw field indicates counterclockwise ordering of vertexcoordinates orientation. Hint: a good debugging technique for problematic polygons is to try changing the value of ccw, which can reverse solid effects (singlesided backface culling) and normalvector direction.
 Warning: consistent and correct ordering of lefthanded or righthanded point sequences is important throughout the coord array of point values.
 Hint: clockwise https://en.wikipedia.org/wiki/Clockwise
 Returns:
 value of ccw field

setCcw
Accessor method to assign boolean value to initializeOnly SFBool field named ccw.
Tooltip: The ccw field indicates counterclockwise ordering of vertexcoordinates orientation. Hint: a good debugging technique for problematic polygons is to try changing the value of ccw, which can reverse solid effects (singlesided backface culling) and normalvector direction.
 Warning: consistent and correct ordering of lefthanded or righthanded point sequences is important throughout the coord array of point values.
 Hint: clockwise https://en.wikipedia.org/wiki/Clockwise
 Parameters:
newValue

getConvex
boolean getConvex()Provide boolean value from initializeOnly SFBool field named convex.
Tooltip: The convex field is a hint to renderers whether all polygons in a shape are convex (true), or possibly concave (false). A convex polygon is planar, does not intersect itself, and has all interior angles < 180 degrees. Hint: concave is the opposite of convex.
 Warning: concave or inverted geometry may be invisible when using default value convex=true, since some renderers use moreefficient algorithms to perform tessellation that may inadvertently fail on concave geometry.
 Hint: select convex=false (i.e. concave) and solid=false (i.e. twosided display) for greatest visibility of geometry.
 Hint: convex polygon https://en.wikipedia.org/wiki/Convex_polygon
 Hint: tessellation https://en.wikipedia.org/wiki/Tessellation

 Hint: number of values must all match for 3tuple spine points, 2tuple scale values, and 4tuple orientation values.
 Warning: if the order of crossSection point definition does not match clockwise/counterclockwise setting of ccw field, then selfintersecting, impossible or inverted geometry can result!
